本發明是有關於一種蓄光材料,特別是有關於一種利用雙鍵立體結構之有機化合物製備多光波長之複合蓄光粉體及其製造方法與應用。 The present invention relates to a light-storing material, and more particularly to a composite light-storing powder for preparing a multi-light wavelength using an organic compound having a double-bonded three-dimensional structure, a manufacturing method thereof and an application thereof.
自從20世紀初長餘輝發光現象被發現以來,蓄光材料的發展取得了快速的進展。各種蓄光材料已廣泛地運用於製造蓄光物體;蓄光材料在吸收了紫外線或其他射線之後可發出光線,此種光線被稱為磷光或餘輝(afterglow)。利用蓄光材料可製成白天可吸收可見光或太陽光、紫外線光,轉換成光能儲存,而在夜晚或黑暗處發出各種色彩的光之蓄光纖維,由蓄光纖維製作的服裝,不僅色光華麗多彩,而且無需染色,避免了環境污染,無毒、無害、無放射性,符合紡織及環保的要求。 Since the discovery of the long afterglow phenomenon in the early 20th century, the development of light storage materials has made rapid progress. Various light-storing materials have been widely used to manufacture light-storing objects; light-storing materials emit light after absorbing ultraviolet rays or other rays, which are called phosphorescence or afterglow. The light-storing material can be used to make light-storing fibers that can absorb visible light or sunlight or ultraviolet light during the day and convert them into light energy storage, and emit various colors at night or in the dark. The clothing made of light-storing fibers is not only colorful, but also colorful. Moreover, it does not need dyeing, avoids environmental pollution, is non-toxic, harmless, and non-radioactive, and meets the requirements of textile and environmental protection.
目前的專利資料中,如中華民國公告第564268號專利所揭露的「高輝度夜光性纖維及其製造方法」,其提供了對人體沒有不良影響,具有長時間高輝度多色發光特性,在刺繡線、衣料用等各種領域內使用的高輝度夜光性纖維。該纖維是由燒成體得到的夜光性顏料的聚酯樹脂或聚烯烴樹脂作芯成分和不含有夜光性顏料的聚酯樹脂作殼成分的芯殼型複合纖維,相對全部纖維,其含有夜光性顏料7~25重量%,從激發停止1分鐘後的殘光輝度為500mcd/m2以上,單根纖維的粗度為40μm以下。 The current patent information, such as the "High Brightness Luminous Fiber and Its Manufacturing Method" disclosed in the Patent No. 564268 of the Republic of China, provides no long-term high-brightness multi-color luminescence characteristics in embroidery. High-luminance luminous fiber used in various fields such as wire and clothing. The fiber is a core-shell type composite fiber in which a polyester resin of a luminescent pigment obtained from a fired body or a polyolefin resin is used as a core component and a polyester resin which does not contain a luminescent pigment as a shell component, and contains all of the fibers. The pigment has 7 to 25% by weight, and the afterglow luminance after stopping for 1 minute from the excitation is 500 mcd/m 2 or more, and the thickness of the single fiber is 40 μm or less.
另外,中華民國公開第20113971號專利所提供的「耐水性蓄光母粒及纖維及其製造方法」,其著重於使用疏水材料,與稀土元素的鋁酸鹽類發光材料進行混合,製作成蓄光母粒,經過熔融紡絲實驗製作成芯鞘型發光纖維;疏水材料可提供蓄光纖維中的蓄光材料免受潮水解的問題。 In addition, the "water-resistant light-storing masterbatch and fiber and the method for producing the same" provided by the Patent Publication No. 20113971, which focuses on the use of a hydrophobic material, are mixed with a rare earth element aluminate-based luminescent material to prepare a light-storing mother.

然而,傳統蓄光纖維往往必須使用高含量的蓄光粉,大約30重量%(w/w),其耗費成本很高,且發光顏色單調,亦無法量化生產, 紡絲和假撚製程容易產生耐熱性不足的問題,而纖維塗佈製程則無法承受耐水洗與加工絲整理等。 However, conventional light-storing fibers often have to use a high content of light-storing powder, about 30% by weight (w/w), which is costly and has a monotonous color and cannot be quantified. The spinning and false twisting processes are prone to insufficient heat resistance, while the fiber coating process cannot withstand washing and processing.
因此,有必要開發出具有高的耐熱性及耐洗性,且發光顏色多樣、容易大量生產的蓄光材料,使得到理想的蓄光纖維或織品,以提高其應用範圍,並提升商業價值。 Therefore, it is necessary to develop a light-storing material having high heat resistance and washing durability, and having various luminescent colors and being easily mass-produced, so that an ideal light-storing fiber or fabric can be improved to enhance its application range and enhance commercial value.

(2)蓄光母粒 (2) Light storage masterbatch
承上述製程,再稱取10~25%之複合蓄光粉體與聚酯(PBT)粉末,並添加具二丙烯或三丙烯官能基之環狀結構試劑0.05~5重量%,及含長碳鏈烷類分散劑0.5~1.5%進行混合,並且添加含三官能基之光敏交聯劑0~3.0%,如表一所示。以雙軸混練機製備成蓄光母粒,混練溫度180~260℃,由於添加了三官能基之光敏交聯劑,使原具有高結晶度之聚酯母粒,於高溫混練環境下產生了自由基交聯反應而產生了內穿透網路(interpenetrating network structure,IPN),使非定型區即非結晶區域增加。接著,所製得之蓄光母粒即進行烘料並測試蓄光母粒發光亮度。由表二之測試結果顯示,由於交聯結構的增加,將使非晶區結構也隨著增加,使複合蓄光粉體於聚酯結構內,因結晶區使發光散射現象減少,而使蓄光母粒發光亮度因交聯結構的增加而增加,並且蓄光母粒的黏度也由0.6增加至0.9,使未來於加工紡絲的幫助非常的高,因為蓄光母粒黏度過稀則將無法成絲。而此發光亮度的顯現不僅增加未來產品的應用性,且可減少複合蓄光粉體的使用量以降低成本。 In accordance with the above process, weigh 10~25% of composite light-storing powder and polyester (PBT) powder, and add 0.05~5 wt% of cyclic structural reagent with dipropylene or tripropylene functional groups, and contain long carbon chain. The alkane dispersant is mixed at 0.5 to 1.5%, and the trifunctional group-containing photosensitive crosslinking agent is added in an amount of 0 to 3.0%, as shown in Table 1. The light-storing masterbatch is prepared by a double-axis kneading machine, and the mixing temperature is 180-260 ° C. Due to the addition of the trifunctional photosensitive cross-linking agent, the polyester masterbatch with high crystallinity is free in the high-temperature mixing environment. The base cross-linking reaction produces an interpenetrating network structure (IPN), which increases the amorphous region, that is, the amorphous region. Next, the prepared light-storing masterbatch was subjected to baking and the light-emitting masterbatch luminance was measured. The test results in Table 2 show that due to the increase of the cross-linking structure, the structure of the amorphous region will also increase, so that the composite light-storing powder is in the polyester structure, and the luminescence scattering phenomenon is reduced due to the crystallization region, so that the light-storing mother is The luminescence brightness of the granules increases due to the increase of the crosslinked structure, and the viscosity of the glazing masterbatch also increases from 0.6 to 0.9, which makes the future processing spinning very high, because the viscous masterbatch is too thin to be silk. The appearance of this illuminance not only increases the applicability of future products, but also reduces the amount of composite luminescent powder used to reduce costs.
